Nabil –
I ordered 200 units of the 12V 6Ah UPS lithium batteries back in April this year. The quality has been excellent , very stable performance, and my customers are really happy with them. Not a single complaint so far.
The only downside was the high shipping cost at that time due to the U.S.-China trade tariffs, which pushed up my overall selling price. If I had placed the order now, I would’ve saved quite a bit on both freight and battery cost. Looking forward to placing my next order around October, hope everything stays stable!
